Neural Regulation01:37

Neural Regulation

39.8K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

3.4K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Neural Control of Respiration01:18

Neural Control of Respiration

2.9K
The neural regulation of respiration is a meticulously coordinated process primarily controlled by the respiratory centers located within the brainstem. These centers, composed of specialized neurons, transmit nerve impulses that control the contraction and relaxation of our respiratory muscles.
Respiratory Centers in the Brainstem
Two primary areas comprise the respiratory center: the medullary respiratory center in the medulla oblongata and the pontine respiratory group in the pons. The...

Neural Circuits

1.5K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Open and closed-loop control systems

963
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Neurulation01:30

Neurulation

42.3K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Area of Science:

  • Robotics
  • Artificial Intelligence
  • Computational Neuroscience

Background:

  • Modularity is crucial for embodied agents, enabling adaptability across diverse domains through transferable and reconfigurable components.
  • Voxel-based soft robots (VSRs) possess inherent morphological modularity, but their traditional disembodied controllers hinder module transferability, limiting their full potential.
  • Existing controllers for VSRs are abstract and difficult to disassemble, presenting a significant challenge for realizing modularity.

Purpose of the Study:

  • To propose a novel self-organizing, embodied neural controller for VSRs that facilitates emergent modularity.
  • To investigate the effectiveness of this controller for tasks like locomotion on rugged terrains.
  • To explore the ability to tune the degree of modularity within the controller and its impact on performance.

Main Methods:

  • Developed a self-organizing, embodied neural controller optimized using evolutionary computation for specific VSR tasks and morphologies.
  • Evolved controllers for two distinct VSR morphologies performing locomotion on rugged terrain.
  • Experimentally analyzed the controller's effectiveness and the impact of adjustable modularity levels.

Main Results:

  • The proposed self-organizing, embodied controller proved effective for VSR locomotion tasks.
  • The controller demonstrated the ability to achieve varying levels of modularity, inspired by biological neural networks.
  • Experimental results confirmed the controller's effectiveness and the tunability of its modularity.

Conclusions:

  • Self-organizing embodied neural controllers can effectively enhance the modularity of VSRs.
  • The emergent modularity in these controllers can be tuned, offering flexibility in robot design and function.
  • This approach lays the groundwork for automated pipelines for assembling, disassembling, and reassembling embodied agents.
